Modified mine to dcen from ac mig. It now welds flux core wire amazingly well. Great for jobs where only 110 service is available. Draw backwards pushing into the puddle with a little higher wire feed and it will produce strong welds with good penetration. Great addition to my shop.
I agree jc. My machine is fun to use with flux core especially those outdoor jobs with only 120V available.
@@DIYHomesteadProjectsDIYHP10 That is fantastic!!!
👍
Bruce I have so much welding coming up. Again thank you so much for this modification also.
Very welcome
Hello. I have same welder . Can I use the stainless still welding wire with this welder? If yes can you send me a link that I can order it please . Thank you
I haven't tried any but they do make flux core ss wire. Here's a link for you. amzn.to/42ElFlT
Actually depending on what you are welding and it's use you can weld SS with regular flux core wire. You won't have the SS properties at the weld so it will rust if exposed to moisture but it will weld the SS metal together.
Hey good video! I came by 'cuz I was wondering if you have ever had any trouble with the feed roller? My dad had to use a vice grip on his. But even then he had to fiddle and fenagle. Fact is that the cheap plastic just doesn't hold up. That whole assembly should be metal. if I ever find some old condemned miller, lincoln or anything with a decent part, I might pick it up and stick it in there.
Probably I'm more likely to just get a decent Mig welder. But I won't throw away the flux core. It'll still come in handy outside in the wind.
Thanks! Fortunately I haven’t had any trouble with the wire feed on this machine. I agree with you that all metal would be much better. But for being plastic and cheap I can’t complain. It’s served me well over the years.
@@DIYHomesteadProjectsDIYHP10 That's good to hear! I hope it holds up because I know it's a common failure point.👍🤙
Converting it to 10 lb spool is awesome
Yes it is! 👍
@@DIYHomesteadProjectsDIYHP10 I have a picture in my mind (& that not necessarily a plan) of using an old reel to reel movie film projector for a wire spool. Could be cool. If I ever did do it I'd want to make it nice and not just slap a bunch of junk together, know what I mean?
Wow that made a big difference.
What is there to convert. I bought my 90 amp and immediately got a 10# spool and it fit. In fact it says it will work in the manual
Hello do you know if the 1 lb spool and 2 lb pool are the same dimensions or interchangeable? Great info thank you
I'm not sure. I've never used a 1lb spool but my guess would be they are the same size spool.
@@DIYHomesteadProjectsDIYHP10 yeah that's what I'm hoping and makes sense to me. Just wondering because I bought a Lincoln electric welder being delivered by UPS tomorrow, that uses 1 lb spools. I'm hoping it's going to also use the 2 lb spools. Using 1 lb spools doesn't make any sense to me. Thanks for the reply
I've never seen any machine that will only use a 1lb spool. I think the 1lb and 2lb spools are the same size but one has half the amount of wire on it. You should be fine with a 2lb spool. The Lincoln wire that comes in a 1lb spool is about twice as expensive as a (non Lincoln brand) 2lb spool. My thought is that Lincoln sells it in a 1lb spool for about the same price as other brands 2lb spools. This is a marketing scheme IMO to make people think they are getting the Lincoln name wire for the same price as an off brand name wire. I've read many posts where people didn't realize the Lincoln is only 1lb of wire and by the time they realize it they can't return it because they have already used some of it. For learning and practice I would suggest using the cheapest 2lb spool of wire you can find. That is what has worked well for me and it will save you quite a bit in wire costs. I wish you the best with your new welder!
@@DIYHomesteadProjectsDIYHP10 okay cool. Amazon had a seller with a great deal the other day. I bought three two lb spools for 20 bucks free shipping. Two days later I checked to see what the price was from the same seller, he raised it five bucks now at $25 for three 2 lb spools
Can the 125 model be modified to run a 10bl spool wire also? thank you
The 125 and the 90 are the same machines with different names. They can both run a 10lb spool with no modifications.
Does anyone know if u can make the Can you make the welding gun on the 90 amp be made detachable and run a stinger ?
Do you recommend using all those capacitors or do you think less would have been sufficient?
From what I understand it's good to have around 60,000 microfarad worth of capacitors. I have seen people have descent results with no capacitors as well. The more you have the smoother the ark is how I understand it. You could always try it without and see if it will work for you and install caps at a later time if you decide you need them. Hope this helps.
@@DIYHomesteadProjectsDIYHP10 AC is fine. I have europan version, and once you found the hot spot settings, something like spray transfer mode, the welds will be very good, and the spatter will be minimal. For my model are, 18.5 volts, wire speed at 6 and 0.9mm wire for 2 mm work steel.
@@yovangeorgiev9607if you don’t convert these little welders, anti spatter spray is a life saver
that looks like it fits easy. I am trying to figure out how to fit a 10lb spool on my titanium 125. I think I got it figured out after watching another video. haha.
Yes a 10lb spool fits easily on the flux 125.
Is this one good for projects and welding tow hitches?
It's good for projects that aren't critical or potentially life threatening if the weld fails. A 90 amp machine just doesn't have the power to weld much over 1/8" in a single pass. An experienced welder might be able to work some magic using skillful techniques but I would recommend a more powerful machine for critical welding such as a tow hitch.
@@DIYHomesteadProjectsDIYHP10 i have the 125 amp,would it still not be good for tow hitches?
The 125 amp and the 90 amp are for the most part the same machine. They are both running off 120V power source and have the same output. HF just relabeled it for marketing purposes to make it look like an upgrade but they are both only capable of 3/16" material MAX with a single pass at best. Most tow hitches that I'm aware of are using steel thicker than 3/16". Personally I wouldn't use any 120V powered welder to weld a trailer hitch. They just don't have the power to achieve the penetration required for a critical part like a trailer hitch. It will stick the two pieces together but it won't have the penetration and strength required for such a weld. Think about it like this, if the weld breaks, could someone get seriously injured? If the answer to that question is "yes" I wouldn't weld it with a 120V powered welder. Again just my personal opinion, I'm not telling you what to do.
@@DIYHomesteadProjectsDIYHP10 ok thank you so much I will be returning it
Sorry, I didn't mean to rain on your parade. I am no expert but through my limited years of welding, I have done a lot of research and study. Everything I've read points to a 240V machine for welding something as serious as a trailer hitch.
You could always ask that same question to one of the "professional" welder channels and find out what they think about it. Then you'll know for sure. Maybe "Welding Tips and Tricks", "Weld.com" or "Pacific Arc TIG Welding". They all have experienced professionals that would know the answer to your question without a doubt. Good luck with your ventures.
Great videos thank you!
Glad you enjoyed and thanks for stopping by!
Nic job and well done 👍 1 only drag 2 torch angle 35 to 45 degrees and your stick out is way to big keep it to 1/2” to 5/8” only make a big difference 👍👍
Thanks 👍
Bought one at harbor freight’s but the flux wire moter just ticks would u know a solution I made shure nothing was to tight or to loose
I would take it back and exchange it if it’s not working right. HF will exchange it for no charge.
I just did the mod for the 10lb spool, and my wire speed is very slow compared to running a brand new 2 lb spool. I have to run the welder at its maximum speed to barely get an acceptable feed rate. I have not investigated the if changing the spool tension makes any difference or not. Might have to upgrade the feed motor to a higher HP to get enough torque to move the 10lbs at an acceptable speed. In the video my estimate is about 6 lbs in left on the spool.
Dang 3/4 in stick out?? Had no idea you were supposed to keep that much of a stick out. I learned something new today
Yes 3/4" for flux core wire. I was a little over that at times but 3/4" is the goal. That's about double the requirement for solid wire mig welding. Flux core wire requires a pre-heat prior to entering the weld pool for the flux to work properly and protect the weld. Flux core wire stick out can be quite long but should not exceed 1 - 1/4" from what I've read.
Thanks for that tip too I've been using this machine as is for sheet metal patches. I other tip for me was smaller size wire .025 Lincoln wire but I don't use gas neither .A thousand bites of welding 101 spot welds really. I'm going to convert to dc should be good. I noticed the little speed motor is 12 v maybe a candidate for a dc relay and 9v battery supply project. Many thanks.
You are quite welcome! Happy welding to you!
@@DIYHomesteadProjectsDIYHP10 Absolutely loovvee the 10lb spool idea. The two pounders just don’t last long enough. Sooo despite not having the “certificates” to be labeled as a “professional” I have spent the last 4-5 years welding in tool/die shops, custom hotrod shops, steel building companies, and everything in between. That being said, the “proper” procedure for fluxcore may say 3/4 of a inch, buutt for me and my experience (just me myself and I, no expert at all) I have found that if I keep the stick out down to like maybe 1/8-1/4 inch and my heat up and wire feed down it starts a pool and burns in much better than it was with a lot of wire hanging out. Just my two cents, no expert at all, but i did buy this same machine when my Lincoln got stolen and I weld thick and/or structural stuff at least once a week with it. Takes lots of cleaning up after, and a good bit of patience, but it’ll weld 1/4-3/8 alllll day. Just in small sections, a couple inches at a time Hahaha
He is running without the nozzle so a little deceptive there.
So, I know this is a year did, but I wanted to tell anyone with this welder that there is a flux core nozzle that will fit. It's the Lincoln Electric gasless nozzle that's available at Lowe's and I believe Home Depot as well. There are two they carry and the one we want is the less expansive screw on cover. The slip on sux butt..
Weld with the tip off burned the factors nozzle up just saying
The fluxcore nozzle for the Harborfreight Titanium 125 welder, can fit the Chicago Electric 125 welder also. You can buy nozzle tips separately.
You should try to keep your gun angle at 15-45 degrees instead of straight up and down. Produces much better visibility and smoother welds thays what works for me
Nice job
Thank you John, I appreciate it!
I just bought a titanium 125 flux I took two back because it won't fire up I checked the tip like instructed touch the tip with the cables no spark at all connected to several grounds changed different outlets you mentioned it must be plugged into a 20 amp circuit some of my circuits are 15 some are 30 I'm assuming I have to find a plug that's 30 don't know can you help me
I would think if it won't fire up on any 120V outlet regardless of the amp rating there is something wrong with the welder. Does the machine start up and fan run when you turn it on?
If it will turn on and the fan runs. When you pull the trigger, does it feed wire out of the gun tip? If it does, feed out a couple of inches holding the tip of the gun near enough so it touches the ground clamp while it's feeding. It should spark and weld. Do this with a welding helmet on for safety and so you don't get flashed. If it sparks when the wire hits the ground clamp, you're good and it should weld. If the wire touches the ground clamp "while it's feeding out of the tip" and it doesn't spark when it hits the ground clamp, something is faulty with the machine. I hope that all makes sense, it's hard to explain.
Washer/Dryer circuit is usually on a 30amp breaker. Washer is 120v. The dryer gets 220v but the breaker should be "30 amp shared" in the panel. Plug your machine into that 120v outlet.
Be careful now you have removed the torch shroud. If you touch the copper bit on the work it will be a total short and can damage the welder. The shroud is Insulated from the copper tip, so touching the work will do no damage.
Will do Dave, thanks for the tip!
I'm thinking that on this unit there is no shorting out with the missing nozzle until you pull the trigger.
That is correct Mike Joyce
It will not damage the welder at all. It will however weld the contact tip to the whatever your welding and kill the tip.
@@tylerturner5442 Been there, done that!
I found out i don't like using the copper coated wire of 0.030 because i believe it takes more heat to melt it and then it's more sloppy i tried it and didn't like it
All the copper coated wire I've seen is solid wire. I have not run across any copper coated flux core wire myself.
@@DIYHomesteadProjectsDIYHP10 I did and it's to splashy and takes more heat than what the machine puts out to make a good weld line the copper coated flux core wire to me doesn't do a good job
I believe it would do a better job in a machine that puts out more heat
It still will get your stuff done but look really sloppy
Can it weld aluminum? 🤔
No
@@DIYHomesteadProjectsDIYHP10 are you sure about that?
If you could find some flux core aluminum wire it might but I don't think that type of wire exists. At least I have never seen any.
Why single pass only with the wire ?
Supposedly if you have more than one pass the weld can become brittle with this wire. That may or may not be a problem depending on what you are welding.
@@DIYHomesteadProjectsDIYHP10Hi. Wanted to let you know there is another type of weld wire with multi pass capability called E71T-11. You can do 3 passes with this type of fluxcore. You may need this type wire down the line for welding on thicker metal to get good weld penetration.
is it better not to use the tip cover? on your lead
It gives you better visibility of the weld pool. You can also see how much stick out you have when you are welding.
They say the fluxcore tips from the HF Titanium 125 can also fit this Chicago Electric 125. Those tips can be bought separately at Harborfreight.
Were is the nozzle at.
i do not see a difference in the welds after the conversion
found it
Glad you found it :)
Third one better.
IT IS TANKLESS, NOT GASLESS !!! ALL PROPER WELDING NEEDS A COVER GAS. THIS IS ACCOMPLISHED WITH EITHER A TANK OF PRESSURIZED GAS, OR BURNING FLUX THAT IS COATED ON THE ELECTRODE OR FLUX INSIDE THE CORE OF WIRE TUBING. AAARRRRRRGGGGGHHHHHH.
